Locked Device Application Display Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The locking and unlocking process of mobile communications devices is time-consuming and cumbersome, frustrating users who need to access information while preventing accidental device activation.
Innovation Solution
A user can request to display an application on a locked device, allowing images generated by the application to be shown while the device is locked, and these images continue to update, enabling users to monitor information without unlocking the device. Additionally, the device can remain locked but display images upon resuming from a power-saving mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the device is locked to prevent accidental activation, then security is improved, but user convenience deteriorates due to time-consuming locking and unlocking processes
Solution Approach 1:
The patent segments the device operation into two independent modes: locked mode and unlocked mode. In locked mode, the device can still display application images and receive specific inputs (like camera shutter commands) without requiring full unlocking. This segmentation allows security to be maintained while enabling selective functionality, reducing the need for frequent locking/unlocking cycles.
Solution Approach 2:
The system performs preliminary actions by pre-configuring which applications and functions should be accessible in locked mode. Users can designate specific applications (like camera or photo viewer) to operate while locked, so when the user needs these functions, the device is already prepared to execute them without requiring a full unlock sequence, thus saving time.
2Reliability
If the device is locked and displays only default screen, then security is maintained, but information accessibility deteriorates
Solution Approach 1:
The patent applies local quality by allowing different parts of the device to have different operational states. Specifically, the display system can show application-generated images and updates even when the device is locked, while the input processing system remains restricted. This creates a localized exception where information display is permitted without enabling full device access, thus maintaining security while improving information visibility.
Solution Approach 2:
The system introduces an intermediary layer between the locked state and application display. This intermediary mechanism selectively permits certain application images to be rendered on the display while blocking other operations. It acts as a mediator that allows beneficial information flow (application updates) while preventing harmful access (unauthorized device control), resolving the contradiction between security and information accessibility.
3Use of energy by moving object
If the device enters power-saving mode, then energy consumption is reduced, but information monitoring capability deteriorates
Solution Approach 1:
The patent implements periodic action by allowing the device to enter power-saving mode with intermittent display activation. Instead of continuously displaying application images, the system can periodically refresh the display at lower power consumption levels while still maintaining the ability to show application updates. This periodic operation reduces average power usage while preserving essential monitoring capability when needed.
Data Source
AI summary
A user request to display an application while the device is locked is received. In response to this user request, one or more images generated by the application are obtained and displayed while the device is locked. Additionally, an indication of an application to be displayed upon resuming operation from a power-saving mode can be received, and an image generated by the application is displayed in response to resuming operation from the power-saving mode.
